The Queensboro bridge connects Manhattan and Queens at 59th Street. The design
features two large cantilever truss spans (1,182 feet and 984 feet) connected
by a 630-foot span over Roosevelt island. The main spans are flanked by
a 470-foot approach span on the Manhattan side and a 459-foot approach span
on the Queens side. Although the original design included trolly and elevated
train traffic, both levels are currently devoted to vehicular traffic with
two pedestrian walkways.
